Journal ArticleDOI
MEMS-based RF channel selection for true software-defined cognitive radio and low-power sensor communications
TL;DR: An evaluation of the potential for MEMS technologies to realize the RF front-end frequency gating spectrum analyzer function needed by true software-defined cognitive radios and ultra-low-power autonomous sensor network radios is presented.
Book ChapterDOI
Q-Optimized Lateral Free-Free Beam Micromechanical Resonators
TL;DR: Laterally vibrating free-free beam micromechanical resonators have been demonstrated that utilize second-mode flexural supports and optimal dc-bias application to suppress anchor dissipation and thereby attain Qs greater than 10,000 at 10.47 MHz as mentioned in this paper.

Micromechanical resonator device
Wan-Thai Hsu,Clark T.-C. Nguyen +1 more
TL;DR: In this paper, a micromechanical resonator device is proposed that utilizes competition between the thermal dependencies of geometrically tailored stresses and Young's modulus to reduce the temperature coefficient (TCf) of the resonance frequencies of the resonator without any additional power consumption.
Proceedings ArticleDOI
Self-switching vibrating micromechanical filter bank
TL;DR: In this paper, a self-switching property of dc-biased capacitive transducers has been used to achieve programmable channel/band selection with only 3 dB of insertion loss, comprised entirely of filter loss.
Proceedings ArticleDOI
Geometric stress compensation for enhanced thermal stability in micromechanical resonators
Wan-Thai Hsu,Clark T.-C. Nguyen +1 more
TL;DR: In this article, a design technique based upon competition between the thermal dependencies of geometrically tailored stresses and Young's modulus has been demonstrated that reduces the temperature coefficient (TC/sub f/) of the resonance frequencies of folded-beam micromechanical resonators without any additional power consumption.
